“…The comparison suggests that this bioproduct adsorbs comparable amounts of perrhenate anions with divalent lead or zinc cations. Amongst the synthetic materials, larger capacities than on S. natans are found for various adsorbents prepared by state of art preparation techniques (Chui et al, 2021; Dong et al, 2020; Gaete et al, 2019; Shan et al, 2019; Weng et al, 2021). They usually require relatively expensive reagents and complex preparation, unlikely the dried metabolite products of bacteria.…”

Aims This study aimed to unveil perrhenate sorption properties of the filamentous sheaths formed by Sphaerotilus montanus, Sphaerotilus natans and Thiothrix fructosivorans. Methods and Results The adsorptions of perrhenate on lyophilizates of the above‐mentioned filamentous sheaths were analysed by ICP, IR, XPS and EDX. The capacity reached 82 mg per g‐adsorbent, when using S. natans. The Langmuir coefficient of this adsorbent was found to be the largest of the three. The adsorption capacity was discussed with respect to the amount of nitrogen and phosphorus in the adsorbents. The occurrence of anion exchange was implied by the IR spectrum changes before and after adsorption. The adsorption data fitted well with a pseudo‐second‐order equation, suggesting that the rate is determined by the chemical bond formation. Conclusions A significant amount of perrhenate was adsorbed on the sheaths formed by S. montanus, S. natans and T. fructosivorans. The adsorption was correlated with the elemental compositions. A strong chemical bond formation was suggested from the results of the Langmuir adsorption isotherm and kinetic analysis. Significance and Impact of Study The capacity obtained for S. natans is one of the largest adsorptions amongst the similar biomaterials, implying the possibility of providing economical adsorbents of rare metal oxyanions.

“…Obviously, the removal performance of Fe 3 O 4 /CTS magnetic nanoparticles to Mo (VI) was good, the adsorption capacity was 35.54 mg/g, which was better than that of D2EHPA-functionalized magnetite (25.8 mg/g) [44], zeolite-supported magnetite (18.02 mg/g) [45], sulfuric acid-modified cinder (31.08 mg/g) [46]. Even though there were adsorbents like polysiloxane modified with DETAP (111.84 mg/g) [47] and QA-MNP (65 mg/g) [35] with excellent adsorption properties, the preparation of these adsorbents might be complex and costly, which was not conducive to production and application.…”

“…When pH<pH pzc , the surface of Fe 3 O 4 /CTS nanoparticles was positively charged, and it was easy to adsorb anions by electrostatic attraction. However, when pH>pH pzc , the surface of the nanoparticles was negatively charged, and the adsorption effect of anion by electrostatic repulsion would be reduced, which tended to adsorb cations [35].…”

“…This suggested that the steps to control the adsorption rate might be limited by the chemical adsorption of shared or exchanged electrons between the adsorbent and adsorbate [14]. The driving force of this process depended on the square of the adsorption vacancy point [35], which could explain the fast adsorption rate in the early stage of adsorption, but in the later stage of adsorption, the decrease of adsorption vacancy points on Fe 3 O 4 /CTS magnetic nanoparticles and the decrease of chemical driving force brought by the decrease of Mo (VI) concentration led to slower adsorption rates [41].…”

Molybdenum is a necessary trace element for both plants and animals and is also an important resource. Nowadays, molybdenum is widely used in China's semiconductor and optoelectronic industries because of its high melting point, high temperature resistance, good corrosion resistance and good thermal conductivity [1]. In addition, molybdenum is found in corrosion inhibitors, fertilizers and alloys [2]. Lianshan District of Huludao City is an important molybdenum industry base in China, accounting for one-third of the country's molybdenum resources. Many molybdenum industry

“…52 The functionalization of Fe 3 O 4 NP s with tertiary (Fe 3 O 4 NP s -A1) and quaternary (Fe 3 O 4 NP s -A2) amine groups was performed according to the procedure reported previously. 53 To obtain the Fe 3 O 4 NP s -A1 catalyst (Figure 1a), N,N-dimethylglycine hydrochloride and Fe 3 O 4 NP s were mixed in water for 3 h at 80 °C under a N 2 atmosphere. To synthesize the Fe 3 O 4 NP s -A2 catalyst (Figure 1b), in the first stage, glycine was incorporated into the Fe 3 O 4 NP s surface using water as a solvent at 80 °C.…”

This work reports the characterization and application of two promising nanocatalysts for the thermal decomposition of ammonium perchlorate (AP). To obtain these composite materials, magnetite nanoparticles (Fe 3 O 4 NP s ) were functionalized with two different amine derivative groups, tertiary amine (Fe 3 O 4 NP s -A1) and quaternary amine. X-ray photoelectron spectroscopy and differential scanning calorimetry provided mechanistic insights into the thermal decomposition of AP. Furthermore, tertiary and quaternary amine groups play a critical role, where the presence of an extra proton could favor an electron−proton transfer as the ratedetermining step. Moreover, Fe 3 O 4 NP s -A1 causes a diminution of the high-temperature decomposition of AP positively to 335 °C, increasing the energy release by 278 J g −1 and consequently affording the lowest activation energy (102 kJ mol −1 ), indicating a low degree of thermal stability, and accelerating the thermal decomposition of AP.
